The 32-year-old showed off her style credentials in a very on-trend ombre top in gradient shades of black, grey and white.

Alessandra
paired the top with a pair of fitted black leggings which were the
perfect attire for her yoga class at a studio in Brentwood where the
model lives with fiance Jamie and children Anja, five, and Noah, 17 months.

The model slipped on a pair of simple black ballet pumps to finish off her outfit and wore her dark locks loose and unstyled.

She's an Angel: The Brazilian model is preparing for the upcoming Victoria's Secrets show so has been amping up her exercise routine accordingly

She didn't appear to be wearing any make-up for the outing and shielded her eyes with a pair of Ray-Ban sunglasses.

Alessandra
toted a large grey leather handbag over one shoulder and a pink and
blue yoga bag over the other shoulder and was seen enjoying what looked
to be a much needed caffeine fix after her work-out.

Whilst
the model didn't wear any jewellery, she did have one very important accessory on her finger - the diamond ring given to her by Jamie in 2008.

Partners: They are engaged and parents to two children, and the duo turned workout buddies in Brentwood

Solid stance: Alessandra and Jamie have been together since 2005 and became engaged the same year they welcomed their daughter Anja into the world

Alessandra and Jamie have been
together since 2005 and became engaged the same year
they welcomed their daughter Anja into the world.

The couple are
often seen out and about together with their adorable children and
despite her demanding career, the Victoria's Secret Angel is very much a
hands on mother.

Family
life aside, the Brazilian beauty has stepped up her exercise
regime in anticipation of the forthcoming annual Victoria's Secret
catwalk show which will be held later this month in New York.

And it seems that Jamie decided to give his other half some moral support as well by fitting in a workout himself.

Close: Despite being the subject of break-up rumours the couple looked closer than ever as they stepped out together on Saturday

Coffee break: Alessandra grabbed a cup of coffee before heading to their car looking great in a gradient sweater with black tights

The Calfornia born businessman looked rather exhausted from all the exercising as he walked ahead of his model fiancee, carrying a towel and rolled up yoga mat.

The
handsome father-of-two was also dressed down for the outing in
camouflage pants, grey T-shirt and brown leather jacket which he teamed
with a pair of green Adidas trainers.

After
the class the duo ran some errands, popping into a few local shops
before heading back home to be reunited with their children.
